摘　　要：介绍了广东粤电珠海金湾电厂2×600MW机组的烟气脱硝喷氨自动控制回路的概况,论述了火电厂选择性催化还原法脱硝系统运行中存在着最低喷氨温度选择、喷氨频繁启/停操作及自动喷氨效果不佳的问题,分析了出现问题的原因,提出了解决方法。The ammonia spraying automatic control loop of the flue gas de-NOxsystem of 2 × 600 MW unit in Guangdong Yudean Zhuhai Jinwan Power Plant was introduced. There were problems in operation of SCR de-NOxsystem of thermal power plant,such as the selection of the minimum ammonia injection temperature,the too frequent start /stop operation of the ammonia spraying system and the poor effect of the ammonia automatic spraying. The problems were described,and the reasons of the problems were analyzed. The solutions were proposed.
